Whakaoti i te 8(1)+(-5(1)-9)=3(1)+[-5(1)-((1)+3)]

$$8 ( 1 ) + ( - 5 ( 1 ) - 9 ) = 3 ( 1 ) + [ - 5 ( 1 ) - ( ( 1 ) + 3 ) ]$$

Whakareatia te 8 ki te 1, ka 8. Whakareatia te -5 ki te 1, ka -5.

$$8-5-9=3\times 1+-5-\left(1+3\right)$$

Tangohia te 5 i te 8, ka 3.

$$3-9=3\times 1+-5-\left(1+3\right)$$

Tangohia te 9 i te 3, ka -6.

$$-6=3\times 1+-5-\left(1+3\right)$$

Whakareatia te 3 ki te 1, ka 3.

$$-6=3+-5-\left(1+3\right)$$

Tāpirihia te 1 ki te 3, ka 4.

$$-6=3-5-4$$

Tangohia te 4 i te -5, ka -9.

$$-6=3-9$$

Tangohia te 9 i te 3, ka -6.

$$-6=-6$$

Whakatauritea te -6 me te -6.
